Bridging fees from ETH to Optimism

The bridging fees from Ethereum to Optimismtic Ethereum can be up to $100 depending on the demand for block-space on the ETH network. With that said, Synapse Protocol is up to 30% cheaper than most other bridges thanks to their innovative interoperability DEX that minimizes slippage across networks.

About Optimism

Optimism is a scaling solution for Ethereum that uses an optimistic rollup to scale transactions and reduce costs. It is being developed by the team at Optimism.io, which is led by former Ethereum Foundation researcher Alex dedicated to building layer 2 solutions on Ethereum.


The Optimism protocol allows users to interact with dapps and smart contracts on Ethereum while keeping their data off-chain. This means that users can enjoy the benefits of decentralization without sacrificing speed or scalability. The team is also working on several other scaling solutions, including a Plasma implementation and a sharding solution.

The layer 2 scaling solution is currently live on mainnet and has an incentives program to help attract total value locked. The Optimism network has over $1 billion in value being utilised on applications on their protocol which includes AAVE, Synthetix, Velodrome, Lyra and others.

Final Thoughts

Using Synapse Protocol is the best way to bridge from Ethereum (ETH) to Optimistic Ethereum. Their advanced DEX platform provides users with low fees, fast transactions and secure transfers of tokens between networks. With their support of stablecoins like USDC, USDT and DAI, there’s never been a better time to cross-chain bridge to the Optimism L2.
